The present application claims priority to Slovak Utility ModelApplication No. PUV 50111-2013, filed Sep. 20, 2013, the disclosure ofwhich is incorporated herein by reference.

TECHNICAL FIELD OF THE INVENTION

The technical solution concerns blanket with protective effect mainlyagainst cold of dorsal parts of human body during sleep.

BACKGROUND OF THE INVENTION

As a result of increased occurrence of civilization diseases, quality ofhuman sleep is deemed very important. In addition to methods of exerciseand various physical activities, the sleep-quality-oriented industry issuccessfully growing. It is focused not only on the quality of bedsthemselves and their equipment, the quality and composition of usedmattresses but also the quality of materials used in the manufacture ofblankets, pads and bed linen.

SUMMARY OF THE INVENTION

It was found that, even when complying with the maximum comfort andquality in bed equipment, neurological symptoms can occur as a result ofthe behaviour of the sleeping person, and/or internal medical problems,as a result of cold of dorsal parts of the human body. This cold iscaused by denudation of the dorsal part of the body, during subconsciousmanipulation with the blanket as we currently know it, mainly due to thefact that the sleeping person that lays on his side, put his leg on theblanket, denudating in this way the dorsal part of his body or partthereof.

These deficiencies are solved by a blanket according to the technicalsolution, which consists of two outer layers of textile. The layers havethe same size and shape and they are firmly connected at theirperimeter. The subject matter of the technical solution consists in thefact that both layers are provided with prolonged opening of the samesize and shape with the same location, which are mutually firmlyconnected also alongside the prolonged opening, too. Suitable size ofthe opening is in the range 50 to 70% of the total length of theblanket. It is appropriate if the opening is narrow.

According to particular sleeping culture that can differ in differentcountries and that is also subject to specific temperature conditions,the blanket as described above, can be sufficient. Well known by us,too, another sleeping culture requires better thermal insulationfunction of the blanket. In such a case, placing at least one thermalinsulation layer is advantageous, between the outer layers, which wouldhave the same shape and the same location of the prolonged opening asthe outer layers. All layers are then connected to each other on thecircumference and on the circumference of the prolonged opening. Mutualconnection of the outer textile layers and the internal thermalinsulation layer further is advantageous, too, using grafting patternsof regular or irregular shape.

The blanket according to the technical solution can have variousmaterial composition. For instance, the outer textile layers may havefibre woven in, which is sprayed by carbon coating, or microcapsulessewn directly in the fibres, with extracts of Aloe Vera cactus. Outertextile layers may be made of natural bamboo fiber combined withmicrofiber. Outer textile layers may be made of combed cotton with finefiber of permanently lustrous fabric with satin weave or they can bemade of synthetic fibres resistant to high temperatures. Fine polyesterfibres so-called microfiber micro-phase is another suitable material.Outer textile layers may be for instance, woven from cotton seed fibres.

The inner heat insulating layer suitable can be made of hollow polyesterfiber. Hollow fiber belongs to the group of profiled fibres. Specialprofiled nozzles are used for spinning, with the possibility to regulatethe size of the cavity, or possibly even the number of cavities in thefiber. The cavity in the fiber affects the thermal insulationproperties. The inner thermal insulation layer can be made ofsiliconised fiber, for better adaptation to the body and more effectiveinsulation, or it can be filled with spherical fiber. The inner thermalinsulation layer can be made of microfiber or fluff, or feather.

According to the particular culture of sleep, the blanket according tothe technical solution can be used with cover, due to hygienicconsideration.

Hence, the technical solution further concerns blanket cover, too, whichconsists of two textile layers of the same size and shape, firmly joinedtogether around the perimeter. Each of the two layers is provided withidentically located prolonged opening of the same size and shape. Theprolonged openings of the both textile layers are equipped with trimmingon their inner sides, with connecting mechanism that mutually connectsthe above opening of the textile layers or that connect own openings ofeach of the above textile layers. This opening on the both textilelayers of the cover serves also for putting on the bed blanket cover.The following are examples of the connecting mechanisms that are locatedalong sides of the prolonged opening that is located in the middle ofthe both textile layers: pair of slits and buttons; zips; rivets orvelcros; etc.

As an example, both textile layers of the blanket can be equipped fromthe following materials. cotton; damask; cotton satin; flannel;microfiber; silk; knitwear material, according to individual taste ofthe user.

When using the blanket according to the technical solution either put incover or not, the user with habit of sleep in position on his side willusually put his knee and part of his leg through the prolonged openingand his dorsal part remains sufficiently covered. When changing hisposition to the other side, legs are exchanged. Experiments showed thatwhen sleeping under such cover, the corresponding movement habit arisesvery quickly.

The cover according to the technical solution can by used for overallcoverage of the blanket. In such a case the prolonged opening shall notbe used. In such a case the connecting mechanism connects own opening ofeach textile layer.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution will be illustrated using enclosed drawings, asfollows:

FIG. 1 shows front view of the blanket

FIG. 2 shows a part of one of sides of the cover with an example ofmechanism of connection using slits and buttons.

DESCRIPTION OF EMBODIMENTS Example 1

Blanket 1 consists of two outer textile layers 11, 11′ that are made ofcombed cotton with fine fiber of permanently shiny fiber fabric. Bothtextile layers have identically made prolonged opening 2, 2′ and theyare firmly connected alongside their circumference 3, as well asalongside the circumference 4 of the prolonged opening.

Example 2

The cover 5 of the blanket 1 consists of two damask layers 51, 51′ thatare connected alongside their circumference 6. Each one of them containsprolonged opening 52, 52′ with side adjusted to use for the blanket 1from example 1. Trimming 521, 521′ is created alongside the prolongedopening 52, 52′, at the inners sides of the two damask layers 51 51′,with connecting mechanism 522, 522′, i.e. two pairs of slits andbuttons.

What is claimed is:
 1. Blanket with protective effect against cold ofdorsal parts of human body during sleep, comprising two textile layersof the same size and shape that are equipped with identically locatedprolonged opening of the same size and shape and are mutually firmlyconnected alongside their perimeters and alongside the perimeter of theopening.
 2. The blanket according to claim 1, wherein at least onethermal insulation layer of the same size and shape is located betweenthe textile layers, which is equipped with identically located hole ofthe same size and shape, wherein all the layers are mutually connectedalong their perimeters and along perimeter of the opening.
 3. Theblanket according to claim 1, wherein all layers are additionallymutually connected by grafting patterns of regular or irregular shape.4. Blanket cover according to claim 1, comprising two textile layers ofthe same size and shape which are equipped with identically locatedprolonged opening of the same size and shape and firmly connected alongtheir perimeter wherein the above openings of the both textile layersare equipped in inner side with trimming with connecting mechanism thatmutually connects the openings of the both textile layers or thatconnects the opening itself of each of the textile layers.
